AB  - By applying the well known dualism: mean count rate - mean time between successive pulses - the equivalence between an IIR digital filter and a preset count digital rate meter has been demonstrated. By using a bank of four second order IIR filters and an optimized automated algorithm for filter selection, a practical realization of a preset count rate meter giving good tradeoff between statistical fluctuations and speed of response, particularly at low count rates such as background monitoring, is presented. The presented solution is suitable for designing portable count rate meters. The designed prototype is capable of operating up to 3600 pulses per second with an accuracy of over 4% in steady-state and responce times of 1 second for the rising edge and 2 seconds for the falling edge of the mean count rate step-change.

AB  - New algorithm for measurement of mean count rate of pulses from radiation detectors is described. The algorithm is based on the control of a bank of digital IIR filters governed by the state of mean count rate-stationary or transient. The algorithm solves successfully the compromise between the contradictory requirements for low statistical fluctuations in steady state and fast response to sudden changes of mean count rate. The design of the bank of IIR filters is carried out by using the Chebyshev approximation of the second kind in order to achieve the high selectivity and high stopband attenuation applying as low as possible order of the constituent filters. All designed filters are of the second order. The static and dynamic characteristics of the new algorithm and the corresponding computational efficiency are tested and compared with those of the traditional ratemeter algorithms. The state of mean count rate, stationary or transient, is determined by a circuit for estimation of the gradient of mean count rate. The numbers of threshold levels within the adaptation logic circuit and their mutual positions have been optimized to achieve the best compromise.

AB  - Two methods developed to improve the classical time constant count rate meters by using the adaptive signal-processing tools are presented. An optimized detection algorithm that senses the change of the mean count rate was implemented in both methods. Three different types of low-pass filters of various structures with adaptive parameters to implement the control of the mean count rate error by suppressing the fluctuations in a controllable way were considered, and one of them was implemented in both methods. An adaptation algorithm for time constant interval calculation was executed after the low-pass filter was devised and implemented in the first method. This adaptation algorithm makes it possible to obtain shorter time constant intervals for higher stationary mean count rates. The adaptation algorithm for time constant interval calculation executed before the low-pass filter was devised and implemented in the second method. This adaptation algorithm enables sensing of the rapid change of the mean count rate before the fluctuations suppression is carried out. Some parameters were fixed to their optimum values after appropriate optimization procedures had been performed. The implemented low-pass filter has variable number of stationary coefficients depending on the specified error and the mean count rate. It implements the control of the mean count rate error by suppressing the fluctuations in a controllable way. The simulated and realized methods, using the developed algorithms, guarantee: a response time not in excess of 2 s for a mean count rate higher than 2 counts/s and a controllable mean count rate error in the range of 4-10%.

AB  - A method for suppression of statistical fluctuations of the mean count rate measurements based on limiting the time difference between two adjacent input pulses to a pre-assigned range, has been incorporated in the preset count digital-rate meter algorithm. The algorithm allows measurement of mean count rates with considerably lower levels of statistical fluctuations of the measurement results and significantly lower values of the preset count compared to the traditional algorithm. The exact relation between the lower and upper limits of the difference between two adjacent pulses has been derived. The lower limit of the preset count applicable to the algorithm has been identified. The response time of the algorithm to a sudden change of count rate has been determined.

AB  - The preset count unweighted moving average (MA) algorithm for digital rate meters has been analyzed and compared to the preset count weighted MA algorithm. The correction factor applicable to the unweighted MA algorithm in order to obtain a final result identical to that of the weighted MA algorithm has been found. It is shown that the response time of the corrected unweighted MA algorithm to an increasing count rate is shorter than that of the weighted MA algorithm. This makes the corrected unweighted MA algorithm suitable for nuclear engineering applications where the slower response of this algorithm to a decreasing count rate need not be considered a shortcoming. The statistical fluctuations in a steady state of the unweighted MA algorithm are found to be somewhat higher than those of the weighted MA algorithm. However, this difference becomes negligibly small for a sufficiently high value of the preset count. (C) 1999 American Institute of Physics. [S0034-6748(99)02209-1].

AB  - The concept of quality of measurement, Q, of the count rate digital measurement algorithm has been applied to the class of preset count digital rate meter algorithms. The best quality corresponds to the minimum of (tau x epsilon) product, where tau is the response time of the algorithm to a sudden change in the average count rate and eis the fractional standard deviation of the steady-state measurement of a constant average count-rate pulse stream. Analytical expressions for tau and epsilon of digital rate meter algorithms are used to calculate maximum values of Q for both weighted moving average and exponential algorithms. The values of the basic algorithm parameters, k for the moving average, and a for the exponential algorithm to achieve these maximum values of Q are derived for both algorithms. A comparison of the present results with the corresponding results obtained for preset time algorithms of these types has been carried out. (C) 1998 American Institute of Physics.

AB  - The definition of the Quality, Q, of a count-rate meter algorithm is introduced as the reciprocal of the algorithms (tau x epsilon) product, where tau is the response time of the algorithm to a sudden change in the average count rate and where epsilon is the fractional standard deviation of the steady-state measurement of a constant average count-rate pulse stream. Analytical expressions for tau and epsilon of digital rate meter algorithms are used to calculate maximum values of Q for both linear and exponential algorithms. The values of the basic algorithm parameters necessary to achieve these minimum (tau x epsilon) products are derived for both algorithms. The use of these values results in algorithms that have relatively short response times and, simultaneously, relatively small steady-state errors. (C) 1997 American Institute of Physics.

AB  - By introducing the ratio of the measurement time intervals of digital rate meter algorithms as an additional parameter, the concept of response-time equivalence for digital rate meter algorithms, linear and exponential, has been generalized to arbitrary measurement time intervals of both algorithms. From the generalized response-time-equivalence relation the bounds to values of the basic parameters of these algorithms, determining the set of parameter values where the concept of the generalized response-time equivalence applies, have been analyzed. An examination of the ratio of the steady-state statistical fluctuations of the current results of these two algorithms showed that it was possible to establish the conditions for the generalized statistical-fluctuations equivalence of the two algorithms. Finally, the conditions for equal response times and equal steady-state statistical fluctuations at arbitrary count rates, defined as the conditions of complete equivalence, have been determined.

AB  - A simple method of starting a new acquisition cycle in microprocessor-controlled frequency synthesising systems in order to suppress the image frequency mode is described. The image frequency detector built into the 305-415 kHz first local oscillator - frequency synthesiser of a 20 Hz - 110 kHz selective voltmeter, supported by an Intel 80C39 microcontroller, identifies the appearance of the image frequency mode in the system and generates a signal to start the procedure carried out by the microcontroller. The microcontroller changes the reference frequency to suppress the signal at the variable input of the phase detector of the phase locked loop (PLL) containing a frequency mixer. This, in turn, forces the phase detector of this PLL to generate an increased voltage, up to 12V, across the associated varactor diode and, by increasing the loop frequency, restore proper functioning of the synthesiser.
